Point of Care

 

Dr. Taylor has worked on a variety of information storage facilities. These technologies include proprietary storage objects used in the Army Research Lab's Digital Battlefield, the University of Maryland's ParkaDB knowledge represenation system, and the Johns Hopkins Hospital Pathology Clinical Data Repository based on Oracle RDBMS technology.  All of these systems use different storage techniques and different method for querying against their respective contents.

Dr. Taylor's experience with the Army's Digital Battlefield was instrumental in developing ad-hoc query evaluation techniques for complex structured data.  The query module that was developed provided a uniform method for querying objects.  It was expressive enough to allow arbitrary combinations of disjunctive and conjunctive clauses on all objects in the Digital Battlefield. 

As one of the primary developers of the current version of the ParkaDB knowledge representation system, Dr. Taylor focused primarily on the underlying database and query engine.  A proprietary relational database system that he co-developed was used to store the contents of knowledge bases that the ParkaDB managed.  His experience with the Parka DB also included the development of a query optimizer tailored for relational joins, selections, and inheritance processing as it relates to artificial intelligence.
